"The second quarter results were in line with our expectations and reflect earnings on our increasing rate base," said Patricia Kampling, Alliant Energy Chairman, President and CEO. "With the solid earnings to date, we are reaffirming 2017 earnings per share guidance."

Utilities, ATC Investment and Corporate Services - Alliant Energy's Utilities, American Transmission Company Investment (ATI) and Alliant Energy Corporate Services, Inc. (Corporate Services) operations generated $0.40 per share of generally accepted accounting principles (GAAP) EPS from continuing operations in the second quarter of 2017, which was $0.05 per share higher than the second quarter of 2016. The primary drivers of higher EPS were higher revenues resulting from Interstate Power and Light Company's (IPL) interim retail electric base rate increase implemented in April 2017 and Wisconsin Power and Light Company's (WPL) retail electric and gas base rate increases implemented in January 2017. These items were partially offset by lower EPS caused by higher depreciation expense and higher energy efficiency cost recovery amortization at WPL.

Non-regulated and Parent - Alliant Energy's Non-regulated and Parent operations generated $0.01 per share of GAAP EPS from continuing operations in the second quarter of 2017, which was a decline of $0.01 per share compared to the second quarter of 2016.

Details regarding GAAP EPS from continuing operations variances between the second quarters of 2017 and 2016 for Alliant Energy are as follows:

Higher margins from IPL interim retail electric base rate increase - In April 2017, IPL filed a request with the Iowa Utilities Board to increase annual rates for its Iowa retail electric customers by $176 million. The request was based on a 2016 historical Test Year as adjusted for certain known and measurable changes occurring up to 12 months after the commencement of the proceeding. An interim retail electric rate increase of $102 million, on an annual basis, was implemented effective April 13, 2017.

Higher margins from WPL retail electric and gas base rate increases - In December 2016, WPL received an order from the Public Service Commission of Wisconsin authorizing WPL to implement an increase in annual retail electric and gas rates of $9 million, each. The retail electric rate increase is comprised of a $60 million retail electric base rate increase and a $51 million monitored fuel-related cost decrease. Effective January 1, 2017, WPL no longer has winter rates that are lower than summer rates. Thus, the quarter-over-quarter variances resulting from the retail electric base rate increase will be larger during the winter quarters, compared to the summer quarters.

    (a)               HDDs and CDDs are calculated
                      using a simple average of the
                      high and low temperatures each
                      day compared to a 65 degree
                      base.  Normal degree days are
                      calculated using a rolling
                      20-year average of historical
                      HDDs and CDDs.
